Hello every1,
as you know i recently replaced my turbo with a new RS2 turbo due to a small crak on the hotside.(im sure paul is still trying to find it,but he will too give up eventually!)
Anyway,i did my 1000kms of slow opening up the new turbo,not pushing it hard and now that i have exceed that amount of kms,i was looking again at the boost gauge for indications regarding my pressure and the boost in general.
I see a good 1.6bar on 5th and 6th gear,around 1.4bar on 4th gear and the 3d goes around 1.4bar and a bit less.I dont bother on 2nd cause it goes up to around 1bar.My vacuum is -0,8 to -0,9bar when driving with gear and not stepping on the gas,while it stays on -0,6bar on idle.(neutral)
Here are my concerns and and questions.
1)anyone that uses the MTM chip,are these good numbers?Are you getting the same figures here or should i be looking at my EM for pressure drops as well,since everything else is changed(samcos,intrercooler mod,new turbo,new WGFV,new dump valve-which is barely noticable i might add,all original parts bought from audi-).
2)if i change the wastegate spring with a stronger one,and keep my MTM chip,what will happen?Will i be getting limp modes all the way?Will i stress the engine?Will i burn the engine?I have found a spring on ebay.de which seems to be the mtm spring,but the seller does not mention.I have seen it matches the mtm spring on other sites though.
3)i also bought me a K&N filter to use on long trips where the air is cleaner.The previous owner did use it and had no problems with it,and also he had bever cleaned it !
4)finally changing the MAF with a bigger,or better one while keeping the rest parts the same,has any effect whatsoever?I mean if i find a sport quattro MAF and use it,without any other changes,what will the effects be on the car?Is it wise?is it stupid?is it useless?
thanks for the time you took to read all that above!
cheers
